电子发射装置以及利用该装置的电子发射显示器
摘要：
本发明公开了一种电子发射装置，其包括基板，形成在所述基板上的第一电极，电连接到所述第一电极的电子发射区域，以及位于所述第一电极之上的第二电极，使得所述第二电极与所述第一电极绝缘。所述第二电极含有开口以暴露所述电子发射区域。第三电极位于所述第二电极之上使得所述第三电极与所述第二电极绝缘。所述第三电极含有与所述第二电极的开口连通的开口。各个所述电子发射区域和所述第二电极同时满足以下条件：D2/D1≤0.579(1)，以及D2≥1μm (2)。其中D1表示所述第二电极的每个开口的宽度，D2表示每个所述电子发射区域的宽度。
摘要（英）：

The invention discloses an electron emission device, which includes substrate, a first electrode formed on the substrate, electron emission region electrically connected to the first electrode, a second electrode on the first electrode, and this structure realizes insulation between the second electrode and the first electrode. The second electrode includes opening for uncovering the electron emission region. A third electrode is located on the second electrode thereby to insulate itself from the second electrode. The third electrode includes opening connected to the opening of the second electrode. All electron emission regions and the second electrode must suffice following conditions: D2/D1 <= 0.579 (1), and D2 >= 1 mum m (2), wherein D1 is the width of each opening of the second electrode, D2 is the width of each electron emission region.
